GeForce RTX 2080 SUPER vs Radeon R9 M385X

Intro

Compare those specifications to the Radeon R9 M385X, which comes with a core clock speed of 1100 MHz and a GDDR5 memory frequency of 1500 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It is made up of 896 SPUs, 56 TAUs, and 16 ROPs.

GeForce RTX 2080 SUPER		316800 Mtexels/sec
Radeon R9 M385X		61600 Mtexels/sec
	Difference: 255200 (414%)

Pixel Rate

The GeForce RTX 2080 SUPER should be a lot (approximately 500%) more effective at AA than the Radeon R9 M385X, and also should be able to handle higher resolutions while still performing well. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Radeon R9 M385X		17600 Mpixels/sec
	Difference: 88000 (500%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
